problems with zoom / layers

Tue Nov 14 13:51:03 EST 2006

ok, i've found that the zoom itself can be the problem.
when i use it, it returns the map extent from map file all the time. i think
when i query, it return to previous map extent, wich is wrong! by the way,
query tool returns the correct map extent:

map extent (map file): -38.234122 -11.52665 -34.594394 -8.133178

test 1.
    zoom:
    minx=-38.676573 / miny=-11.526650 / maxx=-34.151943 / maxy=-8.133178
    query:
    minx=-36.176120 / miny=-9.562008 / maxx=-35.771284 / maxy=-9.258382

test 2.
    zoom:
    minx=-38.676573 / miny=-11.526650 / maxx=-34.151943 / maxy=-8.133178
    query:
    minx=-38.062374 / miny=-9.591776 / maxx=-37.760732 / maxy=-9.365544

test 3.
    zoom:
    minx=-38.676573 / miny=-11.526650 / maxx=-34.151943 / maxy=-8.133178
    query:
    minx=-35.312868 / miny=-8.988244 / maxx=-35.080683 / maxy=-8.814105

(ok, its not the exactly map extents, but the extent less 10% i think - gmap
do this to avoid borders)

so, now, i only have to figure how to use map extent returned from query
replacing the older - the wrong one returned from zoom.

any ideas?

thanks :)
